Security Vulnerabilities in PostgreSQL Shipped with Solaris may Allow
a Denial of Service (DoS) or Privilege Escalation
_________________________________________________________________
Category : Security
Release Phase : Workaround
Bug Id : 6879165, 6879166, 6784052, 6888545
Product : Solaris 10 Operating System
OpenSolaris
Date of Workaround Release : 26-Oct-2009
Security vulnerabilities affecting the PostgreSQL software:
1. Impact
Security vulnerabilities affecting the PostgreSQL software shipped
with Solaris may allow an authenticated PostgreSQL user to cause a
denial of service (DoS) to the PostgreSQL server by "re-LOAD-ing"
libraries from a certain plugins directory. However, the PostgreSQL
versions shipped with Solaris do not include any plugins. In addition,
an issue with the privileges for RESET ROLE and RESET SESSION
AUTHORIZATION operations may allow any authenticated users to gain
extra privileges.
These issues are described in the following documents:
Official PostgreSQL announcement at:
http://www.postgresql.org/about/news.1135
CVE-2009-3229 at:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-3229
CVE-2009-3230 at:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-3230
Note: PostgreSQL is not compiled with LDAP support on Solaris. Solaris
is not affected with CVE-2009-3231.
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
* Solaris 10 (6/06 or later) PostgreSQL 8.1
* Solaris 10 (8/07 or later) PostgreSQL 8.2 without patch
136998-07
* Solaris 10 (10/08 or later) PostgreSQL 8.3 without patch
138826-05
* OpenSolaris PostgreSQL 8.1 based upon builds snv_35 through
snv_109
* OpenSolaris PostgreSQL 8.2 based upon builds snv_56 through
snv_124
* OpenSolaris PostgreSQL 8.3 based upon builds snv_87 through
snv_124
x86 Platform
* Solaris 10 (6/06 or later) PostgreSQL 8.1
* Solaris 10 (8/07 or later) PostgreSQL 8.2 without patch
136999-07
* Solaris 10 (10/08 or later) PostgreSQL 8.3 without patch
138827-05
* OpenSolaris PostgreSQL 8.1 based upon builds snv_35 through
snv_109
* OpenSolaris PostgreSQL 8.2 based upon builds snv_56 through
snv_124
* OpenSolaris PostgreSQL 8.3 based upon builds snv_87 through
snv_124
Note 1: Solaris 8 and Solaris 9 do not ship with PostgreSQL and are
thus not impacted by this issue.
Note 2: A user exploiting this vulnerability must have an account on
the PostgreSQL server.
Note 3: The issues described in CVE-2009-3229 affects PostgreSQL
versions 8.2.x prior to 8.2.14, 8.3.x prior to 8.3.8, and versions
8.4.x prior to 8.4.1.
Note 4: The issues described in CVE-2009-3230 affects PostgreSQL 7.4.x
prior to 7.4.26, 8.0.x prior to 8.0.22, 8.1.x prior to 8.1.18, 8.2.x
prior to 8.2.14, 8.3.x prior to 8.3.8, and versions 8.4.x prior to
8.4.1.
Note 5: PostgreSQL 8.1 (SUNWpostgr), 8.2 (packages beginning with
SUNWpostgr-82) and 8.3 (packages beginning with SUNWpostgr-83) can be
installed at the same time and are separately impacted by these
vulnerabilities.
Note 6: Only systems with PostgreSQL plugins installed are impacted by
CVE-2009-3229 issue.
To determine if there are any plugins installed, execute the
following command:
for PostgreSQL 8.2:
$ ls -l /usr/postgres/8.2/lib/plugins
/usr/postgres/8.2/lib/plugins: No such file or directory
$ ls -l /usr/postgres/8.2/lib/64/plugins
/usr/postgres/8.2/lib/64/plugins: No such file or directory
for PostgreSQL 8.3:
$ ls -l /usr/postgres/8.3/lib/plugins
/usr/postgres/8.3/lib/plugins: No such file or directory
$ ls -l /usr/postgres/8.3/lib/64/plugins
/usr/postgres/8.3/lib/64/plugins: No such file or directory
To determine if a version of PostgreSQL is installed, the following
command can be used:
$ pkginfo | grep SUNWpostgr
system SUNWpostgr PostgreSQL 8.1.9 client programs and lib
raries
system SUNWpostgr-82-client PostgreSQL 8.2 client tools
To determine if PostgreSQL is running on a server, the following
command can be run as the user "postgres" (or the "root" user):
for PostgreSQL 8.1:
$ pg_ctl status -D /var/lib/pgsql/data/
pg_ctl: neither postmaster nor postgres running
for PostgreSQL 8.2:
$ /usr/postgres/8.2/bin/pg_ctl status -D /var/postgres/8.2/data/
pg_ctl: server is running (PID: 395)
for PostgreSQL 8.3:
$ /usr/postgres/8.3/bin/pg_ctl status -D /var/postgres/8.3/data/
pg_ctl: server is running (PID: 395)
or (where applicable):
$ svcs -a | grep postgresql
disabled 17:12:37 svc:/application/database/postgresql_83:default_32b
it
disabled 17:12:37 svc:/application/database/postgresql:version_82
disabled 17:12:37 svc:/application/database/postgresql:version_82_64b
it
online 17:13:05 svc:/application/database/postgresql_83:default_64b
it
3. Symptoms
If the described issue has been exploited to cause a Denial of Service
(DoS), the postgres(1) process may crash, potentially leaving a core
file.
4. Workaround
There is no workaround for this issues. Please see the Resolution
section below.
5. Resolution
This issue is addressed in the following releases:
SPARC Platform
* Solaris 10 (8/07 or later) PostgreSQL 8.2 with patch 136998-07
or later
* Solaris 10 (10/08 or later) PostgreSQL 8.3 with patch 138826-05
or later
* OpenSolaris PostgreSQL 8.2 based upon builds snv_125 or later
* OpenSolaris PostgreSQL 8.3 based upon builds snv_125 or later
x86 Platform
* Solaris 10 (8/07 or later) PostgreSQL 8.2 with patch 136999-07
or later
* Solaris 10 (10/08 or later) PostgreSQL 8.3 with patch
138827-05 or later
* OpenSolaris PostgreSQL 8.2 based upon builds snv_125 or later
* OpenSolaris PostgreSQL 8.3 based upon builds snv_125 or later
A final resolution is pending completion for PostgreSQL 8.1 for
Solaris 10.
